13 - ANOVA Basics - The Grand Mean

In this lesson, we will continue the study of Analysis of Variance (ANOVA) by discussing each part of the calculation separately. Here we discuss the grand mean, which relates the mean of all of the sample means in the data sets.

This will then tie into the sum of squares among treatments and sum of squares of errors in the final ANOVA calculation.

This Professor is the best. He is able to make reasoning very simple!!! I love him!!!

[mervin]

After this tutorial I felt dumb for not understanding this in class…this video is legendary it’s basically ANOVA in it’s simplest form

Thank you so much you have successfully improved my understanding of The Grand Mean! I love your teaching style and how you clearly explain what you're referring to and what it does and how it does it! This video is an absolute 'must-watch' for all students doing statistics!

[kaosiike]

This is amazing. I love how you took your time to explain it bit by bit, like we are all Statistic dummies😅...Thank you so much!

This dude is the man... going through every single step one-by-one... he should be getting paid for that.

[mustafanawzad]

Thanks for your explanation I'm MSc student and I'll use them very much next months because this technique is modern more than other statistical techniques

[maimunajawara]

You guys are just the best !!! Am learning in french but statistics just feels like another language to me but when ever i watched your vidéos, the concept becomes just clear.thank you so much.

[emo_galaxy]

the equation has always scared me away but they are simple once you know. Thanks again!

[kristiluv]

thank you so much, I am starting to understand what is going on

[angeltorres]

love, love, love your explanation. you made it so easy... thank you so much.

[Muuip]

Great explanation, much appreciated! 👍

[caro]

Thanks so much for this detailed explanation on ANOVA!

[adeyemikehindepaul]

using ANOVA approaches calculate the sample standard deviation when the sample sizes are 100, 100, 100 and 100 and the sample mean are 3.85, 2.55, 2.8 and 2.78

[t.sultana]

Thanks for the video. Very comprehensive.

[perrygriffith]

Great video and explanations.

One comment: the mean of all the data points will only be equal to the mean of sample means if the sample size numbers are equal.

Is there an immediate follow-on lesson that picks up where this one left off? I can't find it among the videos posted by "
Math and Science"

[DEVESH]

But your videos are great, tommorow is my exams and youre helping a lot

[acea]

Tq sir... u make statistics sound simple

[alvaroromero]

Dear PhD Math and Science, you explain really good. Thank you
